Siemens 6ES7151-3AA23-0AB0 SIMATIC ET 200S Electronic Amplifier For High-Performance Fail-Safe Digital Output

Product Overview

• Model: 6ES7151-3AA23-0AB0
• Brand: Siemens
• Series: SIMATIC ET 200S
• Type: Interface Module
• Description: IM 151-3 PN ST – PROFINET IO interface module for ET 200S distributed I/O system

• PROFINET IO Device: Supports real-time (RT) and isochronous real-time (IRT) communication
• Prioritized Startup: Enables faster startup of IO devices after power-on or reconnection
• Shared Device: Supports up to 2 IO controllers simultaneously
• Media Redundancy Protocol (MRP): Enhances network availability via ring topology
• Autocrossing & Autonegotiation: Simplifies network setup
• Topology Configuration: Optional for high-performance IRT mode
• Device Replacement: No need for removable media or programming device; device name is assigned by the IO controller based on topology
• Compatibility: Backward compatible with earlier IM151-3 PN versions (e.g., 6ES7151-3AA20/22-0AB0)
